Emmett Louis Till (July 25, 1941 – August 28, 1955) was an African-American boy who was murdered in Mississippi at the age of 14 after reportedly flirting with a white woman. Till was from Chicago, Illinois, visiting his relatives in the Mississippi Delta region when he spoke to 21-year-old Carolyn Bryant, the married proprietor of a small grocery store. Several nights later, Bryant's husband Roy and his half-brother J. W. Milam arrived at Till's great-uncle's house where they took Till, transported him to a barn, beat him and gouged out one of his eyes, before shooting him through the head and disposing of his body in the Tallahatchie River, weighting it with a 70-pound (32 kg) cotton gin fan tied around his neck with barbed wire. His body was discovered and retrieved from the river three days later.

Till was returned to Chicago and his mother, who had raised him mostly by herself, insisted on a public funeral service with an open casket to show the world the brutality of the killing. Tens of thousands attended his funeral or viewed his casket and images of his mutilated body were published in black magazines and newspapers, rallying popular black support and white sympathy across the U.S. Intense scrutiny was brought to bear on the condition of black civil rights in Mississippi, with newspapers around the country critical of the state. Although initially local newspapers and law enforcement officials decried the violence against Till and called for justice, they soon began responding to national criticism by defending Mississippians, which eventually transformed into support for the killers. The trial attracted a vast amount of press attention. Bryant and Milam were acquitted of Till's kidnapping and murder, but months later, protected against double jeopardy, they admitted to killing him in a magazine interview. Till's murder is noted as a pivotal event motivating the African-American Civil Rights Movement.

Bob Dylan ( /ˈdɪlən/), born Robert Allen Zimmerman on May 24, 1941, is an American singer-songwriter, musician and artist. He has been an influential figure in popular music and culture for five decades. Much of his most celebrated work dates from the 1960s when he was an informal chronicler and a seemingly reluctant figurehead of social unrest. A number of Dylan's early songs, such as "Blowin' in the Wind" and "The Times They Are a-Changin'", became anthems for the US civil rights and anti-war movements. Leaving his initial base in the culture of folk music behind, Dylan's six-minute single "Like a Rolling Stone" has been described as radically altering the parameters of popular music in 1965. However, his recordings employing electric instruments attracted denunciation and criticism from others in the folk movement.

Dylan's lyrics incorporated a variety of political, social, philosophical, and literary influences. They defied existing pop music conventions and appealed hugely to the then burgeoning counterculture. Initially inspired by the songs of Woody Guthrie,Robert Johnson, and Hank Williams, as well as the music and performance styles of Buddy Holly and Little Richard, Dylan has both amplified and personalized musical genres. His recording career, spanning fifty years, has explored numerous distinct traditions in American song—from folk, blues and country to gospel, rock and roll, and rockabilly to English, Scottish, and Irish folk music, embracing even jazz and swing.
